Definitions
- the dissolution rate of the surface of the semiconductor substrate is preferentially regulated by the diffusion of hydrofluoric acid contained in a low amount.
- the crystal orientation and electrical conductivity of the semiconductor substrate do not influence the dissolution rate of the surface of the semiconductor substrate. Hence, it is important to stir the dissolving solution.
- the dissolving solution is contaminated with impurities ascribed to the diluent, with the result that the impurity concentration of the background is undesirably increased.
